Hi, I checked your attached file, I think the switch sent a malformed message.
Please check the attached file which is the test result of Open vSwitch.
oxm_length of OFPXMT_OFB_MPLS_LABEL in OFPAT_SET_FIELD is wrong.
oxm_length in your file is 3.
I guess oxm_length of OFPXMT_OFB_MPLS_LABEL must be 4.
In Addition, padding after the Match field is not zero.
Padding of this field in your file is 5de93b7f0000.
I guess the padding fields should be set to zero.
(But this is not root cause of this problem, I think...)
